Hi,
I really appreciate the C++ binding provided.
I got the metal-cpp source code from the website at Getting Started. However, I could not find the same for metal-cpp-extensions. Is it not available or do we have to always extract it from the sample code?
Thanks.

Hello - I’m the Account Holder for an individual Apple Developer Program account. I’m working with freelance junior developers who are building my app in React Native mainly in TypeScript (.tsx) with some JavaScript, with code in GitHub. The app currently runs in Expo Go now.
I’ve been directed to this forum for step-by-step guidance. Specifically I need clear, sequential instructions I can give my developers (and what I personally must do on my Mac) so they can produce a properly signed iOS build for TestFlight (internal testing), and Upload that build to App Store Connect and then submit the release to the App Store.
Context:
This is an individual developer account (not an organization).
I am the only person with a Mac. I added them as developers but was told I need to be the one to upload the final build (is this true, and if so, what do they send me to do that, and when they send it to me, can you please tell me exactly what I need to do from there?)
I was told about Swift Playground, possible SwiftUI conversion if needed, APK file, and using my Xcode for final submission, but not sure what to make of this that will get it on TestFlight from the current React Native.
What I would like to ask for help with is a concise, step-by-step checklist (including exact menu names / commands or tools like EAS Submit, Transporter, or Xcode) of the developers' steps and my admin/account holder steps, so I can hand it to the developers and make sure nothing is missed to get on TestFlight.
I’m on a tight timeline, so any clear, detailed guidance would be extremely appreciated.
Thank you so much. I have looked everywhere and cannot find a step-by-step!
Hi, I am having an issue with xcodebuild -showdestinations command.
Steps to reproduce:
Create a new iOS application project in Xcode or use an existing one.
Navigate to this project in a terminal.
Run xcodebuild -project 'your-project-name.xcodeproj' -scheme 'your-scheme' -showdestinations
What I expect:
All destinations available in the Xcode UI should be listed.
What I get:
It depends. For new projects, I consistently get only generic platform destinations and my connected physical device.
When I run the same command on an older project, I sometimes see all the expected destinations. It seems to be a roughly 50/50 chance between the two outcomes.
Is there a way to get consistent results from xcodebuild -showdestinations? What can I do to ensure all destinations are listed reliably?
Here is a more detailed log and a screenshot:

Hello, I have a question about running tests on multiple simulators.
Currently, my company has a WDIO+Appium test suite with XCUITEST driver that runs on a single simulator through a mockttp proxy (we are intercepting and mocking some of the responses from our APIs and pass through the rest). In order to route the traffic we are currently using 'networksetup -setsecurewebproxy '. Everything works as expected.
With growing number of tests we'd like to scale number of simulators on a single host to 3-5. We have a working setup but the problem are system-wide proxy settings routing traffic from multiple simulators, which we can't distinguish by UDID or any other means, we know of. We can spin multiple mock servers on the same machine but we are struggling to find the way to route the traffic on a simulator basis.
In the end, both options are viable:
1 mock server running for multiple simulators
N number of mock servers for N number of simulators
Has anyone had the same/similar problem? How to approach this? We are currently running on Sequoia OSX and platform version 18.6. Thanks!
Hello Everyone, (and I hope folks at Apple are listening)
So around a year ago, I decided to take on the challenge of creating my own Iphone App from scratch. I am an engineer by trade, and thought it would be a fun interesting experience, and maybe make some money on the side. So I bought a macbook, and focused on learning Swift for the next few months.
Lots of really great developer folks helped me along the way. And I could not have been successful without so much help. It is very much appreciated. So I finished the app, created my own company. And deployed it to the Istore. Unfortunately, just no interest, I think I sold like 4 copies. No problem, still got to learn a lot along the way. So when it came time to renew my developer licence, I let it expire. Just did not make any sense to drop another $100 into it, since only 4 copies had sold in a year.
And then..... this happened!!!! I attempted to use the App that was installed on my own Iphone.... and got the message "My Apps Name" is no longer Available. and it stops... The code is on my phone. I am fully aware that I can no longer use xcode to put anything else on my iphone without a developer licence. But for Apple to reach into my own Iphone, and deny my access to something that I already created, (and in theory already paid for) is just infuriating!!! I checked, and even though it no longer exists in the IStore, purchased copies still seem to function. (one person that bought a copy was a friend of mine). So do I really need to drop another $100, puchase an actual copy of MY OWN APP from the app store, just to have it on my own phone again???!!! So much money and time went into this, that I am considering just smashing every apple product I own, and go with Android instead. I am a single person developer. Almost no one does this sort of thing anymore. Apple used to be the place where innovators could come to try to make something cool and fun to use. I guess not any more.

Hello,
I'm encountering an issue when trying to build and launch a Flutter app on a physical iOS device using Android Studio.
Here is the full log:
`Launching lib/main.dart on (iPhone Name) in debug mode...
Automatically signing iOS for device deployment using specified development team in Xcode project: (Project ID)
Running Xcode build...
Xcode build done. 19.7s
Failed to build iOS app
Could not build the precompiled application for the device.
Error (Xcode): Target debug_unpack_ios failed: Exception: Failed to codesign (Project Names)/build/ios/Debug-iphoneos/Flutter.framework/Flutter with identity (identity ID).
Error launching application on (iPhone Name).`
This only happens when using Android Studio.
When I build the same project using Xcode, it runs fine on the same device.
Background:
I accidentally deleted all Apple accounts from Xcode recently.
In Keychain Access, I had three identical certificates; I deleted the older two and kept the newest one.
I suspect this may be related to provisioning or code signing, but I’m not sure how to resolve it within Android Studio.
Any advice or steps to fix this would be greatly appreciated.
I created a new test project in Xcode using the iOS > App template, enabled automatic signing in Signing & Capabilities, and selected my team.
I then tried building and installing the app on a real device, and it worked successfully.
This confirms that there are no issues with code signing or provisioning on the Apple side.
Thanks in advance!

On macOS, I get a system popup when running UI tests in GitHub saying:
“bash” is requesting to bypass the system private window picker and directly access your screen and audio.
How can I prevent these login and screen access popups from appearing during automated UI tests? Is there an official setup or configuration for running IntelliJ UI tests in CI environments (macOS, Linux, Windows) to avoid such dialogs? My builds run in GitHub Actions VMs, so I can’t manually grant these permissions, and they block the tests.
I try to distribute my App again, but receive now the error that the Minimum IOS is not supported by Info.plist with Runner.
i have latest XCode and the error stays whatever IOS I Set in General and in the building rules.
Any one has an idea or had same issue since recent Xcode / project Updates ?
thanks so much

My app will not open to myself or to clients and has a pop up that claims
"App Outdated"
The app version you are using is no longer supported. Please install he latest Heartland update through the App Store.
However, there have been no updates to the app.

In the availability and pricing section, we have reviewed the plans and we will be upgrading to 50 or 100 million calls/month but before we do, we have a couple questions.
Does the API have rate limit or throttling?
Do you have additional weather forecast endpoints like hail, radar, or pollen forecast? I see in this thread https://developer.apple.com/forums/thread/795642 that air quality is not available
Thanks
When building an app with iOS26 beta3, I received a warning saying "Launch screens will soon be required." Does this mean that, similar to the thread below, the app might not launch in builds for iOS27 and later (including iOS27)? https://developer.apple.com/forums/thread/789004
This browser extension is a doc reading enhancer for the Apple Developer website.
It supports i18n translation, hover link previews, and bilingual display.
Currently, it supports four languages: ja-JP, ko-KR, zh-CN, and zh-TW.
It works with Swift/SwiftUI/Foundation modules now, and it's expected to support Swift Test, Swift Charts, UIKit, Swift Playground, and XCode modules by the end of this month.
For more info, check out: https://appledocs.dev.
You can also visit https://appledocs.dev/progress to see translation progress and vote.
Note: It's only works on Chrome、Edge(In review)、Firefox(In review)

(Copy pasted from FB17261080 that I submitted)
Hi:
Apple's SDK (libSystem.B.tbd) provides definition for multiple symbols(__unw_add_dynamic_fde / __unw_add_find_dynamic_unwind_sections ), but doesn't provide corresponding headers, available in LLVM upstream as libunwind_ext.h
We need such headers to write Exception-Enabled JIT Framework for macOS
I'd like to give control to the app developer that uses my library to select which level of logs they'd like to see from my lib (e.g. do they want to see all debug messages or just errors).
I know there are filtering controls that Xcode gives us, but I'm wondering if there is a way to pull this off with code. Ideally the user callsite would look like MyLib(logLevel: .info).
And then I would pass that info level somehow to OSLog. Today, I create my logger like this:
let myLogger = Logger(
subsystem: Bundle.main.bundleIdentifier ?? "UnknownApp",
category: "MyLibrary"
)
As far as I can tell, there is nothing I can then pass to my myLogger instance to configure the threshold level. I'm imagining an interface like:
myLogger.logLevel(.warning)
// Later...
myLogger.debug("You won't see this")
myLogger.error("But you will see this")
Does OSLog and friends give us any ability to do this out of the box, or are we building little wrappers around OSLog to accomplish this?
Thank you,
Lou
The project at hand is quite complex, and the link content is especially.
I suddenly saw this warning again in recent days and wanted to inquire about when this deletion would be done, so that our team could make preparations and plan in advance.
I have static libraries and headers of a C++ project that I believe are correctly built for iOS and iOS Simulator destinations. The C++ project is built via CMake with something like:
cmake dirName \
-G "Unix Makefiles" \
-B buildDir \
-DCMAKE_INSTALL_PREFIX=installDir \
-DCMAKE_SYSTEM_NAME=iOS \
-DCMAKE_SYSTEM_PROCESSOR=arm64 \
-DCMAKE_OSX_ARCHITECTURES=arm64 \
-DCMAKE_OSX_SYSROOT=$(xcrun --sdk iphonesimulator --show-sdk-path) \
-DCMAKE_OSX_DEPLOYMENT_TARGET=15.0
...
cmake --build buildDir --config Release --target install
I believe those are all the important parameters. This gives me a static library (.a) and headers that I believe should be compatible with arm64 iOS simulators, and I do this same thing for x86_64 architecture with simulators and for actual iOS non-simulator via the iphoneos SDK path.
I'm pretty sure this gives me the correct static lib and headers. Let's assume it does because I'm not able actually create the XCFramework to know if they're right. This does work with a macOS lib and headers, but I need iOS for this library. How do I package this into an XCFramework now?
This Apple developer articles says I should be a able to create an xcframework via xcodebuild -create-xcframework -library libName.a -headers include but when I try to do this with my my iOS arm64 simulator static lib I get:
error: binaries with multiple platforms are not supported '/Users/.../install/ios-arm64-simulator/libName.a
But, when I run: lips -info libName.a I get Non-fat file libName.a is architecture arm64, so, I'm not sure what to do here. Trying to extract arm64 from that static library also produces an error as it it is just an arm64 lib.
I'm not really sure what's going on, but from reading online this specific command, xcodebuild -create-xcframework is a consistent pain point in the process of trying to get an XCFramework, and the seemingly only workaround is to archive a framework project and then create the xcframework via xcodebuild -create-xcframework -archive MyFramework.xcarchive -framework[or -library].
However, how am I supposed to get this static lib and headers into a suitable xcodeproj so that I can archive it correctly? Everytime I try to copy the headers and static lib into the Framework xcodeproj and set what I believe are all the correct settings, my .xcarchive is always empty.
Does anyone have any advice here on how to get this to work?
The main impetus for trying to get this C++ static lib and headers into an XCFramework as that seems like the only valid way to link a 3rd party C++ lib to an SPM package and have the C++ package be interfaceable with Swift.
